Asynchronous teledermatology in an urban primary care practice.

This study evaluated the accuracy, access time, cost, and acceptance by patients and physicians of asynchronous teledermatology referrals in an urban primary care practice. Primary care physicians in a multi-specialty group referred patients for a teledermatology consult. Same-day history and digital images taken by a nurse were electronically sent to a dermatologist who rendered a diagnosis to the physician. Fifty-two patients completed the study. History was adequate for diagnosis in 81% of cases; images were adequate in 75% of cases. Accuracy of the teledermatology diagnosis in cases with adequate images was 97%; accuracy for all cases was 92%. A dermatology visit was recommended in 26% of cases with adequate images, and 42% of all cases. Access time for a teledermatology opinion was 1.9 days versus 52 days for a regular dermatology appointment. Patient and referring physician were highly in favor of teledermatology. Cost evaluations for 20% of patients suggested the cost of a remote consult to be significantly less than the cost of performing an in-person referral. Asynchronous teledermatology may serve as a valuable tool for triage of dermatology referrals and possibly for delivering care to more patients than in urban areas. It can decrease waiting time for a dermatology diagnosis. In an urban multi-specialty clinic-based primary care practice, results suggest the cost of a teledermatology consult is less than that of an in-person service.
